sensitron SMART3G-C2 Gas Detector
Product Information
The SMART3G-C2 gas detector with catalytic sensor is designed to meet
industrial requirements. The enclosure is explosion-proof and can be installed
in ATEX Zone 1 and, when equipped with a dust adapter, in Zone 21. The sensing
element is placed in a stainless
steel head, with two available options: Type head 2 with a 40 mm diameter and
Type head 3 with a 48 mm diameter. The gas detector utilizes pellistor sensors
for flammable gas detection, offering excellent output linearity up to 100%
LEL and fast response time.
The SMART3G-C2 gas detector has a power supply of 12-24 Vdc and a standard 4-20 mA 3-wires output. It can also be equipped with optional serial RS485 communication and a 1 or 3 relays board. The aluminium enclosure has dimensions of 120 x 162 x 90 mm when equipped with Type head 2 and 120 x 184 x 90 mm when Type head 3 is used. The enclosure has 3 cable entries with 3/4 NPT threaded connections.
The gas detector can be ATEX marked as follows: 0722 II 2G Ex db IIC T5 Gb. When equipped with a dust adapter, it is SIL2 hardware and SIL3 software. With a redundant system, the hardware is also SIL3.
